旋翼飞机是一种VTOL飞机,具有直升机旋翼式系统,由其发动机驱动用于起飞和着陆,还包括一个或多个传统螺旋桨,以在巡航飞行期间提供向前推力。在向前飞行期间的升力由转子的组合提供,如旋翼机,以及常规机翼。由于一些问题,对“gyrodyne”一词有一些混淆,复合直升机和复合旋翼机这些术语经常被用来描述相同的设计。 gyrodyne是一些类似的概念之一,试图提供类似直升机的低速性能和传统的固定翼高速,包括倾转旋翼和倾斜。

Gyrodyne

A gyrodyne is a type of VTOL aircraft with a helicopter rotor-like system that is driven by its engine for takeoff and landing and also includes one or more conventional propellers to provide forward thrust during cruising flight. Lift during forward flight is provided by a combination of the rotor, like an autogyro, as well as conventional wings. Due to a number of issues, there is some confusion over the term "gyrodyne", and the terms compound helicopter and compound gyroplane are frequently used to describe the same design. The gyrodyne is one of a number of similar concepts which attempt to provide helicopter-like low-speed performance and conventional fixed-wing high-speeds, including tiltrotors and tiltwings.

In response to a Royal Navy request for a helicopter, Dr. James Allan Jamieson Bennett designed the gyrodyne whilst serving as the chief engineer of the Cierva Autogiro Company. The gyrodyne was envisioned as an intermediate type of rotorcraft, its rotor operating parallel to the flightpath to minimize axial flow with one or more propellers providing propulsion. Bennett's patent covered a variety of designs, which has led to some of the terminology confusion – other issues including the trademarked Gyrodyne Company of America and the Federal Aviation Administration (FAA) classification of rotorcraft.

In recent years, a related concept has been promoted under the name heliplane. Originally used to market gyroplanes built by two different companies, the term has been adopted to describe a Defense Advanced Research Projects Agency (DARPA) program to develop advances in rotorcraft technology with the goal of overcoming the current limitations of helicopters in both speed and payload
